A scary video showing the arm of a baby disappearing under a bed in a darkened bedroom has freaked out a vlogger who left the camera rolling.

Marissa Rachel, who has more than a million subscribers to her YouTube channel is now convinced she is being haunted by a ghost.

In the footage, which was being recorded for her latest video blog, she left the room to get something she needed and left the camera unattended.

Marissa, from Panorama City in California, USA claims as the heavy camera which was placed on a tripod started tipping forward.

It then was showing the area at the bottom of a bed, with what looks like a baby's hand poking out.

But what has scared Marissa, and concerned many of those watching, was what happened next.

Within seconds of the camera panning on to the "arm" it is pulled back under the bed and disappears.

Marissa's online community which watches her vlogs about periods, fashion and dating have shared the clip which has now been viewed nearly 900,000 times.
